BENLYSTA™ (belimumab) Pregnancy Registry

The BENLYSTA™ (belimumab) Pregnancy Registry is a prospective cohort study that enrolls women who have been given (exposed to) commercially-supplied BENLYSTA within the 4 months prior to and/or during pregnancy. This pregnancy registry is a global, multi-center observational study designed to evaluate birth defects, other pregnancy outcomes including: a) spontaneous miscarriage, b) live birth (pre-term birth and small for gestational age), c) stillbirth and d) elective termination, and infant outcomes through age 1 year (serious and/or clinically significant infections). Women at any stage of pregnancy can enroll in the Registry if the minimum eligibility criteria (below) are met. Obtaining information as early as possible in the pregnancy, following informed consent, is desirable. Data will be collected from the participant, the obstetric provider and the BENLYSTA prescriber, and from pediatricians through age 1 year for live births.

Eligibility Criteria:

  • Sufficient evidence to confirm that exposure to commercially-supplied BENLYSTA occurred within the 4 months prior to and/or during pregnancy
  • Sufficient information to classify the pregnancy as prospective or retrospective (i.e., whether the outcome of pregnancy was known at the time of first contact with the registry)
  • Full initial reporter (i.e., pregnant woman or health care provider) contact information to allow for follow-up (name, address, telephone number/email address) and contact information for applicable health care providers if the initial reporter is the pregnant woman
  • Consent provided by the pregnant woman for her participation and assent for participation of her infant
